Privacy Policy

1. Information We Collect

Information you provide. If you email us, or submit feedback from inside the app, we receive the contents of that message and the email address you send it from.

Game and device information collected automatically. When you use the app we and our service providers may collect:

• Device and technical information — device model, manufacturer, operating system version, screen characteristics, language, country and time zone, and mobile network or connection type
• App information — app version and build, installation and session identifiers, and the approximate time and length of your sessions
• Gameplay and usage data — puzzles started and completed, difficulty selected, hints and undos used, mistakes made, solve times, streaks, achievements and daily-challenge participation
• Advertising identifiers — your Android Advertising ID (AAID) and similar identifiers used to select, deliver, cap and measure ads
• Diagnostics — crash reports, stack traces, and performance and stability data

Stored on your device only. Your puzzle progress, statistics, theme, sound, language and other settings are saved in local storage on your device. This data is not uploaded to us and is removed when you uninstall the app.

2. How We Use Information

• To provide, operate and maintain the game
• To save your progress, statistics and preferences
• To display advertising and to measure and cap how often ads are shown
• To understand which features are used so we can improve them
• To diagnose crashes, fix bugs and improve performance and stability
• To detect and prevent fraud, invalid traffic and abuse of the Service
• To comply with legal obligations and platform policies

3. Advertising

The app is free and is funded by advertising. Ads are served through Google AdMob, and we use AdMob Mediation so that more than one advertising network can compete to fill each ad request. The formats we show are app open ads, rewarded ads (which you always choose to watch in exchange for an in-game reward such as a bonus hint) and, where enabled, interstitial ads. We do not show banner ads.

Through AdMob Mediation, ad requests may be sent to Meta Audience Network in addition to the Google AdMob network. When Meta Audience Network takes part in the auction for an ad request or serves an ad to you, Meta Platforms, Inc. receives and processes data as an independent controller of that data. That data can include your advertising identifier, IP address, device and app information, and information about the ad shown and how you interacted with it. Meta uses it to select and deliver ads, to measure their performance and to combat fraud. Meta's handling of that data is governed by its own terms, which you can read in the Meta Privacy Policy and the Meta Business Tools Terms.

Personalised and non-personalised ads. Personalised ads use your advertising identifier and inferred interests to make the ads you see more relevant. Non-personalised ads are targeted using only contextual information such as the app you are using and your coarse location; they still use identifiers for frequency capping, aggregated reporting and fraud prevention. Which of the two you receive depends on your consent choice and on the privacy laws that apply where you are.

Your controls. On Android you can reset or delete your advertising ID, and opt out of ad personalisation, under Settings → Privacy → Ads. Deleting your advertising ID stops ads being personalised, but does not stop ads being shown.

4. Consent (Google UMP)

We manage advertising consent with Google's User Messaging Platform (UMP), the consent management platform built into the Google Mobile Ads SDK. Where consent is legally required — in particular for users in the European Economic Area, the United Kingdom and Switzerland — the app presents a consent form before any ad is requested, and your choice is recorded and stored on your device.

• No ads before consent. The app does not initialise the ads SDK or request any ad until the consent flow has completed and has confirmed that ad requests are permitted.
• Your choice is remembered. You are not asked again on every launch. You can change or withdraw your choice at any time from Settings → Ad Privacy Settings in the app, where the consent form is available again.
• Where consent is not required by local law, no consent form is shown and ads are served in line with this policy and the platform's own advertising controls.

Consent covers Google and the advertising partners disclosed in the consent form, including Meta Audience Network where it is an authorised partner for your region.

5. Analytics, Crash Reporting and Other Services

We use the following third-party services. Each has its own privacy policy, and we recommend reading them:

• Google AdMob — advertising and AdMob Mediation
• Meta Audience Network — advertising, via AdMob Mediation
• Google Firebase Analytics — aggregated usage and engagement measurement
• Firebase Crashlytics — crash and stability reporting
• Firebase Remote Config — remote feature configuration
• Cloud Firestore — storage of feedback you choose to submit
• Google Play Games Services — optional sign-in for leaderboards, achievements and saved progress
• Google Play Services and the Google Play Store — app distribution, updates and in-app review prompts

Google Play Games Services is optional. If you do not sign in, no Play Games profile information is associated with your use of the app.

6. How Information Is Shared

We do not sell your personal information. We share information only:

• with the advertising, analytics and infrastructure providers listed above, so they can perform those functions
• where you have consented, or where sharing is otherwise permitted by the law that applies to you
• to comply with a legal obligation, court order or enforceable governmental request
• to protect the rights, safety or property of our users, the public or us

Our providers operate globally, so information may be processed in countries other than your own, including the United States. Where required, those transfers rely on safeguards such as the European Commission's standard contractual clauses.

7. Data Retention

Progress and settings remain on your device until you clear the app's data or uninstall it. Crash reports and analytics data are retained by Google for the periods set out in their documentation and in our project configuration. Feedback you submit is retained until it is no longer needed to answer you. Advertising data is retained by the relevant ad network under its own policy.

8. Your Rights

Depending on where you live — in particular under the GDPR and UK GDPR in Europe, and under laws such as the CCPA/CPRA in parts of the United States — you may have the right to:

• access the personal data held about you
• have inaccurate data corrected
• have your data deleted
• restrict or object to certain processing, including profiling for advertising
• receive your data in a portable form
• withdraw consent at any time, without affecting processing already carried out
• opt out of the "sale" or "sharing" of personal information for cross-context behavioural advertising
• lodge a complaint with your local data protection authority

To exercise any of these rights, email us at piyushglsict@gmail.com. You can withdraw or change advertising consent yourself at any time from Settings → Ad Privacy Settings in the app. Because the app has no accounts, we may need additional information to identify the data associated with your device before we can act on a request.

9. Children's Privacy

The Service is not directed to children under 13, and we do not knowingly collect personal information from them. The app is not listed in Google Play's Designed for Families programme. If you believe a child has provided us with personal information, contact us and we will delete it.

10. Data Security

We use commercially reasonable measures to protect information, including encrypted transport (HTTPS/TLS) for data in transit and the access controls provided by our infrastructure providers. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

11. Changes to This Privacy Policy

We may update this policy from time to time. The revised version will be posted on this page with a new "Last updated" date, and significant changes will be highlighted in the app or on this website.
